JDBC Connection from Oracle 11g Java Stored Procedure

When using a Java Stored Procedure from within the Oracle 11g database, an attempt to open a connection to Teradata using the JDBC driver version 14 throws the following error.
Exception in thread "Root Thread" java.lang.NullPointerException

The connection code is:

create or replace and compile java source named "TDTest" as

  // Required class libraries.

  import java.sql.*;

  import oracle.jdbc.driver.*;

  import oracle.aurora.util.*;

  import com.teradata.jdbc.*;

  public class TDTest {

    public static int requestPriceDetails(String anchor, Integer rc, Integer sg, String upc, Integer req_id) throws SQLException {

      com.teradata.jdbc.TeraDriver td = new com.teradata.jdbc.TeraDriver();

      String tdConnectionString = "jdbc:teradata://tddev1cop1.ngco.com";

      Connection tdConn = DriverManager.getConnection(tdConnectionString, "user", "password");

      return 0;

    }

  }

The same code works run using the Oracle JVM on the same server. Is there a parameter that needs to be passed in this JVM?
